    Re: DUCKWEED, which one ?

    I should of said....flowing slowly....guess it doesn't like 'a lot' of flow.
    Likes 'some' shade....I've got to get mine covered before it get's too hot.


    I don't remember 'where' i got this link (somewhere in DIY, maybe?) ... It's from Fishfarming.com

    Shorter article, good basic info....on duckweed.

    Now that I have both types of duckweed I see that the tilapia will go through and pick the small stuff out and eat it first.

    Wolfia is best, but very hard to keep out of the beds. I have a larger duckweed I collected from Virginia about 5 years ago. Very hearty. I'm happy to share for the cost of shipping. Be quick as it gets cold here soon. Right now it is $5 for a flat rate box. Soon it becomes express and expensive.

    Some Filipino Methods

    We run our lesser with the larger together and harvest whichever grows quicker.
    We have a converted container with bottom flow/bottom drain/constant height
    on line with AP system.



    Azolla is another favorite of our tilapia that grows well in duck weed conditions.
    Some we grow in our large pond with our bigger fish so we just keep it netted
    from the bottom so that fish don't eat all our crop!

    I don't know any numbers, but I believe duckweed offers nitrogen fixation, which means it does not pull as much nitrogen out of the water... or maybe it might even put some into it? I'm still doing research, but just food for thought!
